The question asked, verbatim: best error monitoring tools for agencies

Brands named, in the order the engine gave

1. Sentry mentioned
   Sentry - The default, and for most agencies the right answer.
2. WordPress mentioned
   It covers basically every stack a client project might use (JS/React, PHP/Laravel, WordPress, Rails, Python, iOS/Android), and its org → project structure maps cleanly onto "one org, one project per client." Source maps, release tracking, and session replay are all in the box.
3. Self-hosted Sentry mentioned
   Self-hosted Sentry or GlitchTip - Specifically for agencies, because this is where the economics flip.
4. GlitchTip mentioned

5. Rollbar mentioned
   Rollbar - The one I'd pick if Sentry's bill is the problem but you don't want to self-host.
6. LogRocket mentioned
   LogRocket - Add this alongside an error tracker, not instead of one, and only for clients with real frontend complexity (e-commerce, dashboards, SaaS).

The answer, as recorded

## The short list, in the order I'd actually recommend them **1. Sentry** - The default, and for most agencies the right answer. It covers basically every stack a client project might use (JS/React, PHP/Laravel, WordPress, Rails, Python, iOS/Android), and its org → project structure maps cleanly onto "one org, one project per client." Source maps, release tracking, and session replay are all in the box. The catch for agencies is pricing: it's metered by reserved event volume with a shared pay-as-you-go budget on top, billed separately across errors, spans, replays, and logs - so one client's misconfigured service can eat the quota you bought for everyone. Set per-project rate limits and spike protection on day one. ([Sentry pricing overview](https://checkthat.ai/brands/sentry/pricing), [comparison](https://www.stackfyi.com/guides/error-tracking-sentry-vs-rollbar-vs-bugsnag-2026)) **2. Self-hosted Sentry or GlitchTip** - Specifically for agencies, because this is where the economics flip. GlitchTip is Sentry-SDK-compatible, so your client code doesn't change - you just point the DSN somewhere else. Run it on a $20-40/mo VPS and you serve 30 client sites for a fixed cost instead of a per-event bill that scales with your client count. Worth it once you're past roughly 10 projects; below that the ops overhead isn't worth the savings. **3. Rollbar** - The one I'd pick if Sentry's bill is the problem but you don't want to self-host. Cheaper entry point (~$13/mo tier), simpler occurrence-based bands rather than several separately metered products, and solid grouping/deduplication. Weaker on frontend depth and replay than Sentry. ([Rollbar](https://rollbar.com/blog/sentry-alternatives/)) **4. LogRocket** - Add this alongside an error tracker, not instead of one, and only for clients with real frontend complexity (e-commerce, dashboards, SaaS). Its value for agencies is political as much as technical: when a client says "the checkout is broken," you send them a video of the session instead of a stack trace. That ends arguments fast. ([Better Stack roundup](https://betterstack.com/community/comparisons/error-tracking-tools/)) **5. AppSignal** - Best fit if your agency is concentrated in Ruby/Elixir/Node. Per-app pricing with unlimited seats is unusually agency-friendly, and it bundles APM, uptime checks, and logs, so it can replace two or three tools. Narrower language support is the tradeoff. ([AppSignal via Better Stack](https://betterstack.com/community/comparisons/error-tracking-tools/)) **6. Raygun** - Worth a look if clients want polished reports. Crash + error + real user monitoring with good code-level detail, and the reporting is presentable enough to forward to a non-technical stakeholder without reformatting. ([Sauce Labs roundup](https://saucelabs.com/resources/blog/the-best-error-reporting-and-crash-monitoring-tools-of-2026)) **7. Firebase Crashlytics** - Only if you ship mobile. Free, and there's no reason to pay for mobile crash reporting when this exists. Pair it with one of the above for the backend. **Who I'd skip:** Datadog. It shows up on every "best of" list, but it's an enterprise observability platform priced per-host - the wrong shape and the wrong cost for an agency running many small client projects. BugSnag (now SmartBear Insight Hub) I'd also skip now that pricing isn't publicly listed and you have to go through sales for every quote. **The agency-specific thing most lists miss:** decide early whether client error data lives in *your* account or *theirs*. Billing it to your account is simpler and lets you monitor everything in one dashboard, but it means you're holding their production error data - which can contain PII - and you own the migration headache when the relationship ends. Provisioning in the client's own org and getting invited as a member is cleaner on both counts, at the cost of dashboard-hopping. I'd default to the client's org for retainer clients and your own for short projects.
